One more time credits to AllGamer

http://dl.dropbox.com/u/14913717/i9023.doc

Edit :I finally managed to post the guide here as well

First thing first :Credits goes to AllGamer and j_r0dd and of course to kursk who first wrote down the steps.

I am not an android expert/developer, just a user trying to help other guys.

I see a lot of guys asking /having problems with rom manager (3.0.0.5 or 3.0.0.6). Yes its true so just use the CWM version from here and DONT try to install and update rom manager from the market.

This guide applies to nexus s i9023 (slcd) on Windows 7 (i am running the 64bit version) and of course if you decide to root your phone and unlock your bootloader is at your own risk. You may end with a bricked phone. The guide following worked for me and of course took the risk of a brick .

At the end of the guide you will find a few instructions in order to flash your phone to stock with Odin.

!!!!!!!First check that your computer has already installed the Microsoft.net framework 4!!!!!!!!

1. Download Java SE and install

https://cds.sun.com/is-bin/INTERSHO...ProductRef=jdk-6u24-oth-JPR@CDS-CDS_Developer

2. Download Android SDK. Install the .exe file as administrator and right down to a piece of paper where your installation is (i propose to install it at C:\Android\android-sdk)

http://dl.google.com/android/installer_r10-windows.exe

3.Select to run SDK manager

4.You are going to have a popup window asking for some updates.

5. Make sure you select the “Accept All” instead of the default “Accept” in order to download and install the google driver. (image below)

6. Let the SDK finish the installation

7. Then check the following folder

C:\Android\android-sdk\extras\google\usb_driver

Here is the google usb drivers

8.Then go to C:\Android\android-sdk\platform-tools and copy-paste the adb, AdbWinApi.dll and AdbWinUsbApi.dll to C:\Android\android-sdk\tools.

After that your C:\Android\android-sdk\tools must be like the image below

9.Go to Start>Computer right click Properties and then Enviroment Variables

Go to System Variables and find the “Path”, select edit and at the end of the line just add ;C:\Android\android-sdk\tools (with this way the “adb” is executable from everywhere).

10. Go to Start and type cmd and then right click “run as administrator” and then type adb

11. From here http://xdaforums.com/showthread.php?t=728929 download the usb drivers for Samsung (select the 32bit or 64 bit depending your system) extract the zip and run the setup.

13.Now lets go to our phone. Go to Settings>Applications>Development and enable the “USB debugging”.

14. Connect your phone through usb and at the same time open your device manager of your pc.If your device manager shows “Other devices” and below that “nexus s” do a right click and Update Driver software

And then Next.

After that you are going to see

15. Turn off your phone . Hold volume up and then power button to boot in bootloader.Then connect your phone through usb to your pc.

You are going to face in device manager the below image

Ok don’t panic.Right click Update driver software>Browse my computer for driver software

Then Let me pick from a list of device drivers on my computer ,then select Android phone

And then Android Bootloader interface

After that device manager is going to be like the below

16.Then open a command prompt (CMD) and switch to the directory C:\Android\andoid-sdk\tools.

17.Type fastboot oem unlock

after few seconds you are going to see on your phone

Use volume keys to select and power button to apply.

After finished (it takes very little time) you are going to see LOCK STATE-UNLOCKED

And on CMD

•	... OKAY [435.433s]

If for any reason you hang up after fastboot oem unlock,you can try another usb port or maybe another cable.

18.Download from here

Be careful !!!!The 3024v3-i9023 and NOT the 3024v3-i9020

Rename it to recovery.img and put it in C:\Android\android-sdk\tools

Open a CMD again (if you close it) and switch to C:\ Android\android-sdk\tools

And type fastboot flash recovery recovery.img and then hit enter

You are going to see on CMD something like that

•	sending 'recovery' (3980 KB)... OKAY [ 0.621s]
